President Trump once again pressed Senate Republicans to install a 51-vote threshold to pass legislation on Saturday, in a flurry of tweets that claim the current setup is controlled by the Democrats.

"Republicans in the Senate will NEVER win if they don't go to a 51 vote majority NOW. They look like fools and are just wasting time," Trump tweeted in the early hours of the morning. "8 Dems totally control the U.S. Senate. Many great Republican bills will never pass, like Kate's Law and complete Healthcare. Get smart!"

For days now, the president has pressured the leadership to end the filibuster, which requires 60 votes to break. The president also said that budget reconciliation, which lets bills be approved in the Senate with only 51 votes instead of the 60 needed to stop a filibuster, is "killing" the Republicans in the Senate.

"200 Bills sit in Senate," he tweeted. "A JOKE!"

If the Senate Democrats ever got the chance, they would switch to a 51 majority vote in first minute. They are laughing at R's. MAKE CHANGE!— Donald J. Trump (@realDonaldTrump) July 29, 2017

Trump did not specify who the eight Democrats are, but said that if Senate Democrats were in charge, they would make the switch to a 51-vote majority in the "first minute" and that they are "laughing" at Republicans.

Democrats did approve the "nuclear option," or abolish the filibuster and instill a simple majority requirement, when they were in charge of the Senate in 2013 for all nominees, except Supreme Court nominees. Republicans went "nuclear" in April to help advance Neil Gorsuch to the Supreme Court.

Despite Trump's overtures, there has been little appetite in the Senate to go "nuclear." In April, Senate Majority Leader Mitch McConnell, R-Ky. said there is "no sentiment" to tackle the filibuster rule for legislation.

Trump's latest effort follows the Senate Republicans' failure to pass a healthcare plan that sought to make progress on repealing and replacing Obamacare. However, the "skinny bill," which failed late Friday, only required 51 votes to pass. Three Republicans, Sens. John McCain of Arizona, Susan Collins of Maine, and Lisa Murkowski of Alaska, voted against it.
